Calculate a credit-weighted grade-point average from the grade points and credits assigned to each course. Use the numeric grade points supplied by your institution.
A GPA is a weighted average. Each course's grade points are multiplied by its credits to produce quality points, so a higher-credit course has a larger effect on the result.
This calculator accepts grade points directly. It does not convert letter grades or percentages because grading scales vary among institutions and countries.
Calculate this value separately for every completed course.
Quality points = grade points × course creditsAdd all quality points, then divide by the total credits represented by those courses.
GPA = Σ quality points ÷ Σ course creditsA 4.0 in a 3-credit course contributes 12 quality points, a 3.0 in a 4-credit course contributes 12, and a 3.7 in a 3-credit course contributes 11.1. The total is 35.1 quality points across 10 credits, producing a GPA of 3.51.
Copy the numeric grade points from your institution's grading policy or transcript.
Use the credit hours or course weights that count toward the GPA you are calculating.
Your institution decides how repeated, pass/fail, withdrawn, or transferred courses affect an official GPA.
Courses do not contribute equally when their credits differ. For example, a 3.0 grade in a four-credit course influences GPA four times as much as the same grade in a one-credit course.
There is no universal GPA ceiling or letter-grade conversion. Some institutions use points above 4.0, so this calculator allows any nonnegative grade-point value and does not label a result as good or bad.
Multiply each course's grade points by its credits, add the quality points, and divide by total credits.
Only when every course has the same credit weight. Otherwise GPA must be weighted by credits.
Yes. The calculator does not impose a 4.0 cap because institutional scales vary.
Yes. Enter any positive decimal credit value used by your institution.
Yes. Zero is a valid grade-point value when paired with positive credits.
No. Enter grade points directly using your institution's own scale.
It calculates the weighted GPA only for the rows you enter. It does not combine a previous cumulative GPA with new coursework.
Follow your institution's rules. Do not enter courses that carry no grade points or are excluded from GPA.
Institutions may have specific rules for rounding, repeated courses, transfers, or excluded coursework.
Results show up to four decimal places without unnecessary trailing zeros. Internal calculations retain full precision.
